Natural Pearls In the past, natural pearls were collected by pearl divers primarily in areas around the Persian Gulf and the Red Sea. Pearl divers would travel on a pearling vessel for weeks at a time, collecting shells from pearl beds. The shells were opened on board and the proceeds of the discovered pearls were split between the crew - not evenly, however. Today, natural pearls are primarily found as a byproduct of the fishing industry and to a smaller extent, local, intentional collection - especially in Central America. Cultured Pearls There are two varieties of cultured pearls; saltwater and freshwater. Their harvesting methods vary slightly. 1. Saltwater

Saltwater pearls are bead-nucleated pearls grown in the reproductive organ of saltwater mollusks. This is an organ in the body of the mollusk known as the gonad. When a pearl is harvested, the shell is opened slightly, an incision is made to the gonad and the pearl removed. In the case of Tahitian and South Sea pearl culture, a new nucleus is often inserted and another pearl is grown. In the case of akoya pearl production the mollusk is not renucleated. 2. Freshwater

Freshwater pearls are tissue-nucleated pearls grown in the mantle tissue organ of freshwater mussels. This is the large muscle that attaches to either side of the mussel's shell. Because this muscle is large, it may accept many implants, up to 16 on either side of the valve. When freshwater pearls are harvested, small incisions are made on the mantle and the pearls removed. Often the mussel is returned to the water to grow a second, bead-less regenerated pearl, or a CBSB beaded freshwater pearl.

Do mollusks die when pearls are harvested?

Mollusks do not necessarily die when pearls are harvested, but the process can be harmful to them. If the pearl is removed carefully and the mollusk is healthy, it may survive and even produce more pearls in the future. However, in some cases, the harvesting process can lead to stress or injury that might result in death. Additionally, not all species of mollusks can survive multiple harvesting attempts.

How is a cultured pearl different from a natural pearl?

Natural pearls grow in the wild, without any human assistance or interferrence, and are quite rare and can be difficult to find. When found, the pearls are harvested, cleaned and made into jewelry, and cost more than cultured pearls.Cultured pearls are grown ('cultured') under highly controlled conditions by pearl farmers. Farmers plant a core (a 'grain') made up of mussel shell into an oyster or mussel; then the oyster or mussel forms a pearl around this irritant, just as they do when forming natural pearls.Pearl farmers design cultured pearls from start to finish to ensure they are perfect in shape and luminosity. After they are harvested, the pearls are cleaned, and some are treated and bleached (to ensure continuity of color, quality, etc.) before being made into jewelry.Both natural and cultured pearls can be freshwater or saltwater pearls. Freshwater pearls are created or occur in mussels, while saltwater pearls are created or occur in oysters.

How are akoya pearls harvested?

Akoya pearls need to be grown in salt water and survival rates of the oysters in farms are very low with only 5% of pearls produced going on to be made into jewellery. Oysters are generally produced in a "farmed" environment where a tissue is inserted into the centre from a previously producing oyster. After 18 months this is transformed into a new pearl and ready to harvest.
